starting problem on countax ride on lawnmower

[kilotango]

hi, tried a different battery, the starter is not pre engaged, it throws th cog into the flywheel at least it used to! the solenoid is a seperate unit when the ignition is turned on a voltage goes to it, the other half of the coil is grounded. you can hear the contactor working and a multimeter shows that it puts the voltage to the starter motor.
it is strange, i am fairly convinced that both starter motors have failed - but why is the puzzle?
cutting an acre of grass with a push mower is not great!

Hi Stephen, have you solved the starter engagement?
I Have exactly same issue and a similar field to mow...
Contactor clicks, starter fly's up but engine turns to slow to start. Battery vitals are fine.
Starter, checks out ok, & it fly's to engage.
I am going to try with the plug out to see if engine turns over faster with less resistance.
Next, I will change dc contactor to eliminate this as an issue.
Please let me know if you got to bottom of problem?

it turned out new starter was duff. if petrol is getting into chamber (dirt in carb) then it will create high resistance.
use car jump leads to bypass other leads. one from battery to starter body, one from live battery and just touch the live input on starter. this will show if any permanent leads are duff i suspect solenoid is ok
